Hello, all! I hope this post finds you well. I had a single level ALIF at L4-L5 on November 24th, so I am approximately 9.5 weeks post-op. On Monday I started riding the recumbent exercise bike at home for 30 minutes daily to start trying to drop some weight. That is the only change I have made and my back pain has slowly started returning, to the point I'm likely reaching for the hydrocodone tonight. How could the bike be causing this issue? I don't want to stop (surgeon and I both know the weight has to come off if I want success in the long run), but obviously I don't want to be in pain again! Is this temporary as I get back into exercise? Any thoughts? Tips? Thanks!
